Specification of Letters Patent.

Patented July e, 1915.

Application filed December 23, 1912. Serial No. 738,131.

l show cases, and particularlyto such cases in which the walls or sides are lcomposed of glass or marble, in whole or in part.

The especial object of the improvements embodied herein is to produce a show-case for articles of food which require refrigeration for proper-preservation, in which the contents will be clearly visible to the customer, and readily accessible to the clerk without requiring the opening of doors.

A further object is to provide a sanitary show-case, in that -all the exposed parts are of non-absorbent material and are so designed and combined as to be readily disassembled and thoroughlyl cleaned.

A still further object is to construct a show-case in which the cold-air produced by suitable refrigerating means connected therewith will be effectively circulated throughout the case while any 'heat in the articles placed in the case will be permitted to freely escape. I

still further object of the improvementsv embodied herein, is to provide a show-case of handsome appearance, and one in which is combined a small counter convenient for handling, cutting or wrapping the articles removed from the show or storage chamber.

Other objects of general utility are conserved by my invention which will be apparent to those skilled in the art.

In the accompanying drawings, I have illustrated a preferred embodiment of my invention in the following views:

Figure 1 is a vertical transverse section through my improved show case; Fig. 2 is a sectional detail showing the manner of connecting the front plates with a supporting bracket; Fig. Sis a sectional ldetail showing the meansfor fastening the front and divivso sion plates together; Fig. 4 is a sectional detail showing the manner of connecting the top plates with a division plate; Fig. 5 is a sectional detail showingl the connecting means between. the endvof a top-plate and a vertical end-plate; Fig. 6 is a sectional detail of the connection vbetween the lower qualities.

which are constructed of any suitable material and in any approved manner adapted to furnlsh the required strength and insulating Within the chamber 9 are arranged the refrigerator pipes or coils 10, which are supported by suitable brackets The walls 9a support a marble slab 11, which serves asa-counter for use by the clerk inhandling the articles removed from the show-ease. If desired, this counter may have its lower surface exposed to the direct miuence of the refrigerating chamber 9, so that it may be kept at a'low temperature.

The show-case proper, is built up of glass plates which form the front, top, end and division Walls, all of which are connected and braced by metal members, as will now be described. Assuming a show-case of twenty or morefeet in length, the front -wall will be composed of several glass plates vtoform a curved edge 15, at the upper and inner corner of the case. At suitable intervals, I place within the case, brackets 16, the base 16a of which rests upon and is secured by screws to the case bottom 8, the vertical portion 16b supports the front wall plates 12, and the top member 160- supports the top, plates 13.

Referring to Fig. 2, it will be seen that the vertical portion 16" of the bracket,f16, straddles the joint between the vertical edges of two of the plates 12, and is tapped to receive screws 17 which pass throughv .fiat metal straps 18 overlapping the edges of the plates 12, so that when the screws 17 are tightened, the L margins .of the glass plates 12 will be firmly clamped between the strap 18 and the bracket 16.

Referring to Fig. 3, which shows the method of connecting a division plate 15 with two Ifront wall plates 12, it will be seen that 18a vrepresents a flat metal strap.

similar to the strap 18 but not so heavy, which bridges the joint between the edges of the plates l2, and which is pierced by holes to receive the screws 17a'which enter bosses 19a extending outwardly from the clip base 19 between the adjacent edges of the plates 12. The base 1) is secured to the bottom of the right-angled lclips 20, the flanges of which embrace the opposite sides of the plate 15. The connections between the angle-clips 20, and the plate 19, are made by screws which pass through suitable slots within clipsv 20 and engage tapped holes in the plate 19, thus providing for adjusting the clips to it glass of varying thickness, this arrangement being identical with that shown in Fig. 6 in connection with other clips.

Referring to Fig. 4, it will be seen that the abutting margins of two top plates 13 are connected and supported by an anglebracket 21, which in turn is connected with two angle-clips 22, by the screw and slotted arrangement above described in connection with the clips 19 and 20.

In Fig..6, the lowermargin of the glass plate 15, is shown clamped by angle-clips 24, in which are slots 24a to receive the screws by which said clips are adjustably attached to the plates 25, the latter having threaded holes to receive the attaching screws.

The referencenumeral 26 represents an angle or corner bracket which is fitted to the outer corners of the top plate 13, and receives the screws which connect the clips 22, in the manner described in connection with the bracket 2l, with which it differs only in that the bracket 26 has two vertical walls, while the bracket 21 has but one. The lower margin of the end-plates 14, are held by a clip 27 which is screwed to the base 8 by screws 28, and by a second clip 28 which tits against the inner marginal wall of the plate, 14, and is adjustably connected with the clip 27 by screws 28a.

It willthus be seen that I have provided a series of clips for clamping the margins of the glass plates which constitute the walls of my improved show case and that I have provided for inequalities inl the thickness of .these plates by having at least one of a pair of complementary clips adjustable relative to the other.

or braces 16 will be placed at such intervals as to effect the desired strength in the finished show-case, while their shape or design issuch as `to occupy but little of the space within the show case.

In the use of my improved show-cases, it

opening along the edges 15a' but little of the cold air from the refrigerator chamber 9 escapes to the atmosphere, owing to the greater specific gravity of said air, the course of circulation being indicated by the arrows in Fig. 1. The constant pressure of the cold air within the case also serves to effectively exclude flies from the case. If there should be any latent heat in the meat or other articles placed in the case, it will rise to the top of the latter, and escape at the rear opening at a point just below the top plates 13.

It will be understood that the clips 20, 22, 24 and 28 extend the full length or width of the plates they embrace, except where their ends abut, in which case one of the plates is -cut off to prevent the overlapping which would otherwise occur.

Having thus described my invention what I claim as new, is

1. A device of the kind specified comprising an elongated display case consisting of a top wall or counter, a front wall, a bottom arranged ina plane parallel with said top or counter and of greater width than the same, and dividing walls arranged at substantially right angles to said front wall, and a compartment disposed at the rear of and parallel to said case and open to and communicating with the same along its side facing said case.
